To all Lo/wm t may concern.'

lic itknown that I, hmmm ltonmrrsoN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga` and State of Ohio, have invented a certain new and useful Improvement in Labeling-Machines, of which the followiiw is a full, clear, and exact description, reterence being had to the accomjmnying drawings.

'lhis invention relates to labeling machines and jnnticularly to machines adapted for attaching labels to loaves ot bread, cakes, pies and other bakery j n'oducts, although adaptable within the scope of my invention for attaching labelsto parcels, boxes, bolts -of cloth, rolls ot paper, and many other articles.

The object oi the invention is to provide a` machine olf this character in which all the parts shall cooperate to the end in View with the least possible danger ot the machine being so operated as to act prematurely with the consequent loss of labels, damage to product, or d erangement of parts; and, more specifically, to provide a machine in which any desired number ot labels within a considerable range may be applied simul taneonsly to articles ol' the nature upon which the machine is intended to operate, said labels being automatically ted, cut, transferred to the articles, and ailixed thereto.

Another object of the invention is the provision, in a device of this character, of mechanism whereby the operation of the label at'lixing means shall be prevented until the article to be labeled has been moved to the exact position intended and whereby said operation is innnediately and positively performed as soon as that position is reached, while other objects and advantages of my invention will be made apparent in the course'of the following description and claims.

One embodiment of my invention is illustrated in detail in the drawings accompanying and forming a part of this application, although it is to4 be understood that the machine illustrated therein is only one out of many devices by the use of which the principle of my invention may be employed, and that many variations in matter of form and arrangement of parts may be made Without departing trom the scope of my invention.

:ln said drawings, Figure l is a right hand Fig. 3 is a rear elevation of the complete machine, a portion of the table flange being broken away; F101 l 1s a bottom plan vleW of the table; F10. o 1s a central vertical cross sectional View o the machine taken substan- -tially on the line 5--5 of Fig. 3; F ig. 6 is a top plan view of the label feeding means, the upper feed roller and cutting knlfe being re moved; Fig. 7 is a detail cross sectional view through the label feeding and cutting means; Fig. 8 is a detail View of an element of the label feed; Fig. 9 is a. perspective view of the label transferring arm and associated parts; Fig. l() is a detail View of the trictionclutch; Fig. .ll `is a perspective view of the trigger and associated parts; and Fig. 'l2 is a detail view illustrating the method of preventing premature operation of the machine and insuring its operation at the proper time.

Describing the, parts by reference characters, l indicates a tlat table, preferably of m'ctal and having a depending lip or flange 2 therearound and having supporting legs 3.-

Mounted adjacent the ends of this table are the vertically extending tlat end plates 4 and 5, respectively, which are connected by the longitudinally extending horizontal rods 6 so as to form a rigid frame. Secured to the top ot' the .table parallel to the end plates 4 and 5 are the guides 7 7 secured by thumb screws S projecting` through longitudinal slots t) formed in the table so as to permit their adjustment toward or from each other. ln these drawings l have illustrated the muchine as adjusted for attaching labels t0 loaves ot' bread, and l have illustrated the usual bakers set consisting of three pans, l0, l0" and l0", secured together in a row by means otl metallic straps ll and containing six loaves of bread; and the guides 7 are arranged so as exactly to permit the passage of one of these sets therebetween. Slidably mounted upon the rod 6 and adjustablysecurable thereto are the :labeling units l2, one of which is arranged in operative relation to each loaf of bread which is passed thereunder. I have illustrated six such labelingr units in this machine. thglLht is obvious that, since the)7 are all exactly alike., the machinecould be made larger or smaller within any desired limit, and that in case' smaller sets be used, it is possible to slide the unused units to the end `of the machine and leave them there. Each of-these sets comprises a frame made of a horizontal plate 15 having upstanding ears lo and 16a sleeved upon the rod 6 and having depending side pieces 17 between which is secured a shell or hood 18 having an open bottom spaced a short distance above the top of the pans.v

The sides of this hood preferably consist of flat plates 19 connected at the top by a curved plete 2O and having their forward edges connected' together by means ofvv a brace :21 provided with a flat inwardly eX- tending shelf 22. i

Secured to the forward end of the plate 15 is a pair of brackets 23 upon which is mounted a. roll il of labels, thel width of which must be less than the width between the plates 19 of the hood. .lournaled in the end plates d and 5 and extending through the plates 19 is the label `transfer shaft 25, here shown assquare in cross se tion although any polygonal, grooved, or splined shaft could obviously be employed. Sleeved upon this shaft inside of each hood is a sleeveQG from which projects a radial arm 27 adapted to receive the label from the label feeding device, transferv it to the bread or other article, and aflir it thereto. This arm is preferably made ofv wire, shown in lli-g", l), and has upon its outer end a plurality of lingers 28 adapted to swing by' other' lingers 29 secured to the brace 2l. The length of this arm is such, as to cause it when in normal position, to res't upon the shelf :22 and the position of the shaft 25 is such as to cause the end of the arm to contact with the bread or other article at the Y desired point.`

ils will now be apparent, the operation of,

the machine is to deposit e severed label upon the linger 2.9, and then swing the arm 2T so as to transfer the label to the surface or the bread, and the means for accomplishing these two steps, and of timing their pere forinanoc both with relation to each other and. to the. presentation of the bread will now be 'lescribed. f

Journaled in brackets 30 ,secured to the bottom of the table is a longitudinal shaft El having at sulistantially the middle` point 33 and and the corresponding side finies of the gear 32 the friction disks 39 are inten. posed. Each of these collars is provi les.

witha radially extending arm adapted to be engaged by dogs vor stop lmembers which shall arrest their rotation, while the gear 32 is in mesh with the pinion l1 or a motor eiland 1s driven thereby continuously.

Secured between the end plates Lland 5' and spaced above the table l is a horizontal shelf e8 about which is grouped the label feeding means. The rear edge of this shelf abuts against the upper outer edges of the braces 2l, as shown in vFig. 5, and parallel with this edge of the shelf isa longitudinal slot. 49 inwhich is mounted the lower label feed rolle-r 50. This roller is 'preferably supported in eccentric bushings 5l carried by the end plates 4l and VE and also has at one end inside one of the plates a gear wheel 52, as illustrated in Fig. 7." immediately above this roller is journaled parallel com panion roller 53 provided withv a, gear 5st meshing with the gear 52 and havingone of its journal studs, as 55, extended through one of the end plates, as 5, and there provided wit-h a ratchet'wheel 56. Journaled von this stud immediately inside of the` ratchet is a lever 57 having thereon a, pawl adapted to engage said ratchet Wheel and connected by a link 58 with a reciprocable rod 59 extending upwardly through the table and slidably mounted in a boss 60. A spring 6l is preferably associated with this rod so asl to hold it in upward position, and a lever 62 pivoted at G3 to a bracket 6l rigidly carriedby the table is slidably journaled to its lower end, as at 65. secured to the end ofthe shaft 3l bears against a roller 67 carried. by said lever G2 and serves to produce one complete recipro-A cation of the rodl) at each revolution. T he point of contact of the rollers and comes substantially at the top of the table a8, as shown in Fig. 5, and the pit-ch of the ratchet wheel is so selected that at cach actuation thereof, said rollers will be atl-- -vanced a sulhcient distance to deliver one label to each of the different units.

The rear edge of the table 4S is provided with a tlat horizontal cutting plate 70, as shc vn in .5, ll and Y, and the 'end plates -4 and 5 are provided with vertical slots 7l immediately above the plate. fr horizontal beam 7:2 is projected through these slots and runs from end to end of the machine,-

A cam 6G y ics l groove 80 of an internal cem 81 secured to the shaft 31, said cam being so designed as to cause one complete reciprocation of the rods 74- at each rotation.

Secured to the side of thevbeam 72 is a` cut-ting knife 85 adapted to pass by the edge of the cutting plate 70 and shear ott a label at each reciprocation, and mounted immediately at the side of said knife is a spring pressed foot'or cushion 8G adapted to press the label strips against'the plate 70 and hold them during the cutting operation. This foot or cushion is preferably secured to the beam 72 'by bolts 87 passing slidably through Vertical perforations therein and is held. in downward position by springs 88 surrounding' said bolts. The lower edge of .this foot or cushion is preferably provided with a. surface of rubber or other soft material 89. It will now be obvious that, at each rotation of the shaft 81, one label will be fed into each of the units 12 by the action of the cam Gti, rod 59, lever 57, and ratchet wheel l50, and that after such feeding, said labels' will be severed by the knife 85 and will drop upon the fingers 29. f

Secured to the end of the shaft 25 outside of one of the end plates, 5, is a pinion 93 meshing with a rack 91 carried at the upper end of a reciprocating` rod 95 sleeved in a hollow 'boss 90 and held in mesh with said pinion by means of a roller 97. The lower end of this rd is articulated to a lever 98 provided with a roller 99 engaged with the cam (iti and preferably held in downward position by means of a .tension spring 1.00. The otherend of said lever may conveniently be journaled by loosely slccving the same upon the shaft 78, as shown at 101. With the arrangement now described it will be seen that at each rotation of the shaft 31 the rod 95 and rack 94 will be moved downwardly under the influence of the spring 100 so as to rotate the shaft 25 and cause the arms 27 to pick up the labels from the fingers 29 and transfer the same to the top of the loaves, or other articles to be labeled. Ity is necessary, however, that this shaft be actuated but once for each sct of tins introduced into the inachine, and that this actuation should not take place until thc tins have been moved sutiicicntly far to permit the arms 27 to clear the edges thereof, otherwise the arms will be damaged by contact with the metal. It is further necessary that means be provided to prevent the operation lof the label atiixing means until the tins have been delivered to the machine at the proper angle, otherwise some of the transfer levers might be damaged. And, furthermore, it. is desirable to lock thcanachine against a second operation in case the attendant after having labeled one set of loaves should draw that; set back a short distance instead of passing the same across the table to an attendant, as in the usual manner. The mechanism by which these results are obtained will n0w be described.

Secured to the bottom of the table adjacent each of the arms 40 is a bracket 105 having a dog 10G pivoted thereto. The lower ends of these dogs are provided with teeth 107 adapted to engage the arms 40 and the upper ends thereof with toes 108 adaptedlto be engaged. by projections 109 carried on bars 110. The forward end of each of these bars is provided with laterally extending fingers 111 projecting into slots 112 formed in the sides of the bracket 105, the forward ends of these slots being formed with upwardly inclined surfaces 113. The rear ends of these hars are articulated to cranks 114, secured to the ends of separate rock shafts 1.15a and 1.15", which are journaled to the bottom of the table adjacent the rear edges of the hoods 18. Secured to the outer end of each of these rock shafts is a trigger arm 11G, here shown as provided on its forward face with an extended bearing plate 117 for engagement with the backs of the pans. Each of these triggers is preferably provided with a spring 11S for drawing the same forwardly and each of the dogs 10G is provided with a spring 119 for swinging its tooth. into engaging position. If a set of tins be introduced into the machine and pressed against thc triggers 110 the bars 110 will be pushed forwardly and thc dogs 10,0 swung so as to release the arms 40 and permit the rotation of the shaft 31 by rason of the frictional engagement with the gear 32. y

Referring to Fig. 2 and the direction of rotation of the shaft marked thereon it will be seen that the first action which takes place is the moving of the sharp nose of the cam (SC past the roller 99 so as to pern'iit the spring 100 to actuate the rack 94 and operate the label transfer arms 27. These arms then pick up the labels from the tin gers 29 and slap them down upon the surface of the loaf, as above explained. The customary practice is to atlix the labels bcfore thc bread is baked so that the natural adhesiveness of the dough may hold the labels thereon without the need of any special gum or glue. The continued rotation of this cam causes the oppositely inclincd surface thereof to return the lever 98 to its original position and with it the rack 94. and arm 27. As the cam (to con tinues to revolve the sharp nose thereof passes the roller (i7 permitting the upward mov-ement of thc-rod 59 so as to enable the pawl on the lever 57 to engage the next succeeding tooth on the ratchet 50, after which this arm is again moved downwardly so as to feed one label fromcach of the rolls 24. It will bc noted that this label is not4 fed' iiorivardly until after the arms 27 have been returned to their normal position, as it is imperative that the labelsv be not fed be hind these arms. Als soon as the arms 62 and rod 59 have been moved downwardly to their normal position, the cam 81 Will have moved to a position to actuate the rr. ls Z4 and thereby the cutting knife 85. This cutting operation may be performed either at the beginning of the cycle of operations or at the end thereo. It is merely necessarythat'tbe cutting knife be actuated .fitter the labels have been projected through the rollers and before the actuation of the transfer arms 27. ln thepresent embodiment, l have illustrated the cam 81 as set vte perform this operation at the beginning oi 'the cycle, but this arrangement is riot imperative.

lnasniuch as the shaft Bl'began to move the' instant the dogs 106 were released,- l.. proceeded at once to the explanation of the cycle'of operation Without stopping to consider what happened to the dogs themselves. `In case the triggers 116 are tripped simultaneously, the dogs 106 are releasedat the same instant and the shaft 31 moves the arms tar enough so that it. is' impossible for the dogs to catch these arms' again. lt is necessary, however, that these dogs be so arranged as to insure their catching the arms at the end et thatv revolution irrespective o1' Whether the bread has or has not been removed, otherwise, a negligent attendant might pile up a quantity of labels upon each loaf. This end is secured by reason of the inclined side 113 of the slot 112 which euses the ingers 111 to raise the end of .the rod 110 so as vto disengage the project-ion 109 from the toe 10S and permit the spring 112 to return the dog to its original positions lt is possible, however, that the at tendant might frustrate this arrangement by bach the loaves slightly away from the 1113 and, by pressing them or we; again, obtain a second actuation of the machine 1n order to prevent this contingeney, l forni the rear of the trigger arms 116 with boolrs 120 adapted to be engaged by latches 121 pivoted to brackets 122 formed in the Arear ot the triggers and pressed into locking position by springs 123; These latches are provided with upwardly curved releasing arms 1211 projecting slightly above the tops of the brackets. When the bread pans are shoved against these triggers the latter are locked by means of the latches 121, though not until the dogs 106 have been released from the projections 109, as above explained. The operation ot the machine takes place in the ordinary manner, the loaves being delivered thereto by an attendant positioned at the liront thereof, but only one operation can by any possibility be had until the arms 12e have been depressed so as to release the triggers. A sec.- ond attendant stands at the rear of the machine and removes the loaves, lifting them slightly so as Vto draw them from the tops ot the brackets 122. r1`he Weight of the loaves causes the arms 124i to be depressed, thereby releasing thetriggers as above de scribed. 7The springs 118 then return the bars 110 to their original position, the projections 109 riding over the ends of4 the dogs.

Une other contingency remains to be avoided: Supposing the tins be inserted at such an angle that one Qt the triggers is tripped While the other one is lefturitouched; the corresponding dog 106 will go through all the motions ot'releasing its corresponding arni /10 and the aliected trigger will be loelred back by the latch 121. The shaft. 31 will, however, have been held against rotation by the other dog so that `the dog will immediately snap bach into its original position beneath its arm, and the machine held against operation, `inasinuch as the projection 109 would now be upon the wrong side 'ot the'dog. Consequently, ist the attendant were then to shove the pan around straight so as to operate the farther trigger, the second dog would momentarily release its arm but the shaft would still ,tail to revolve because of the enga gement or' the first dog. 1n order to prevent this contingency; l provide the expedient illustrated in Figs. 5 and 12 which consists in providing each of the arms i0 With a pivotcd blade 130 mounted in a recess formed in said arm and limited in its down-- Ward swinging movement by means of a projection 181. The outer end of this blade is arranged to form practically a Continua tion ot the `arm. el@ so that it the arm :tails to move the 'instant the dog 106 is released therefrom, the blade 130 will tall so as to prevent the rengagemenlt ot the dog therewith, as shpvvn in Fig. 12, and the shaft will be tree to rotate the instant the other dog'is disengaged In connection with the label. feeding means l have illustrated an expedient tar starting the labels thereinto and insuring their being severed atthe proper points.

lie

Mounted in a longitudinal slot at the outer edge ot the shelf 48 is a small starting roller 135 and 'above this roller is aseoond roller 136 carried at one side of a tiltable frame 13T which is journaled between lugs 138 and 139 formed on the top of said shelf. rlhe side of said frame adjacent the feed rollers is provided With a stop plate 140 and the roller 136 is provided with a milled hand Wheel 141. Pivoted to the lug. 139'is alever 142having at its inner end a pair of spaced` fingers adapted to engage a'lug 1613 fcarried by the trame and having at its outer end a set screw 144:

v'said projection." The end of said lever is limit the linsertion of the labels and permit.

them to be started evenly. The lever is then swung toward the rear of the machine so as to press the startmg rollers 135 and 136 together whereupon the hand wheel 141 is turned to bring the labels into such proximity with the feed rollers 50 and as to permit them to be grasped thereby. The distance between the feed rollers 53 and the cutting knife 85 is preferably equal to a whole number of labels, though it is obvious l that the machine could be started under otherl conditions by properly'cutting the y rstlabels inserted. After the knife 85 has cut one label along the proper line, it is necessary merely to have rollers 5() and 53 of the proper size as compared with the pitch of the ratchet 5G to cause all succeeding labels to be cut with equal exactness. The cutting plate 70 is preferably made slightly adjustable, as shown in Fig. 6, so as to allow for grinding and adjusting.

For purposes of description and in the name of greater clearness, I have illustrated the cams 66 and 81 as separate fromeach other and secured to opposite ends of the shaft 81. It is obvious, however, that the cams vcan be formed together as a single piece, and the same will doubtless frequently be done in practice. Furthermore, I have illustrated the machine as trigger operated, though it willv be obvious that it might be made to operate continuously upon a time basis without departure from my invention, and reliance placed upon the attendant or upon some type of feeding device for presenting the loaves thereto with sul'licient regularity.l It will also be obvious that the machine could be adapted for the attaching of labels to other' articles than loaves of bread within the scope of my invention. And, furthermore, while I have necessarily described my invention in detail I do notl propose to be limited to any such details except as the same may be positively in eluded in the claims hereto annexed or may be rendered necessary by the prior stat-e of` the art.

Having thus described my invention, I claim 1.
